I have had a yellow gorgonian for several months now and I have never seen it open more than 10 or 15 polyps at a time. I see pictures of them online and they have all of their polyps out. I put food in the tank daily, and it is in moderate flow. Is it unhappy or is this normal? I know that it is non-photosynthetic, but does this mean that it cannot be directly in light? Any help is appreciated.
